Luminescence and Luminescent Materials

Journal of Electronics and Control, 1958
ABSTRACT A general review of luminescent materials is given, with some emphasis on the more recent applications. The theoretical aspects of the absorption and emission processes are discussed briefly.

Visual Luminescence and Luminescence Imaging

2013
Visual luminescence excited by UV light and luminescence imaging are discussed as simple and effective techniques for preliminary characterization of diamonds and as methods of recognition of HPHT-treated diamonds. Since all natural diamonds fluoresce under UV excitation, the visual luminescence technique is a common method applicable to diamonds of ...

Efficiency of luminescence in luminescent solar concentrators

Applied Optics, 1983
The power efficiency of luminescence excited by solar radiation in luminescent solar collectors is calculated for a glass sheet doped with Cr3+. The achievable chemical potential for an optically thick absorber irradiated by diluted blackbody radiation as a function of Cr3+ concentration, sheet thickness, sunlight dilution, and luminescence quantum ...

Thermostimulated Luminescence and Tunnel Luminescence

2001
A very characteristic feature of XL of natural and synthetic diamonds is delayed light emission with time constants of tenths of minutes. This delayed luminescence results from TL and TSL. The contribution of TL in the delayed luminescence of synthetic diamonds is 90% (Vins 1988; Yelisseyev and Sobolev 1979b; Yelisseyev 1977; Vins and Yelisseyev 1989 ...

Luminescence

Physics Today, 1964
The first international conference on luminescence ever to be held took place in Poland in 1936. This was pointed out at the opening of the 1963 International Conference on Luminescence last September 25 in Torun, Poland, by Alexandra Jablonski, president of the Organizing Committee, and the man after whom the diagram used by every worker in the field ...
